Fairly unknown. Bought it from a guy who was converting a Boxster to electric. Prior to install, I replaced most of the external things like thermostat, water pump, AOS, AOS pipes. I bore scoped, pulled the pan, and replaced the IMS bearing. The only thing that raised a red flag was some sludge in the pan but it did not go higher than a couple of inches in the sump. My hunch is that the oil rings are stuck and that is only because I don’t believe that stem seals could leak that fast to create the amount of smoke that is being produced. My next idea is to kill each cyl 1 at a time by disconnecting coil and injector to see if any 1 cyl smokes more.
